I have Suzuki Liana LXi (1600CC) which have landirenzo CNG kit installed. My car was fine both on CNG and petrol before long shut down of CNG in punjab. As these days I am going to KPK weekly where I use CNG but there is jerking problem on CNG. Pick is very bad, can not climb on a small slope, and the serious problem is that it often take a heavy jerk (Jhattka) from the engine in 2nd gear. I have 3 times checked to CNG mechanic who had done CNG setting many times, Air intake opening have closed 2/3 portion, changed advancer "lovatto tomasetto CIP 4 SMB", have changed new spark plugs and air filter, but all the problem still remains.
Car is fine on petrol but milage on petrol is not good i.e 8 km/L in city, 12 km/L on highway.
One thing to tell you that my enginge has crossed 100000 kms and it needs to replace piston rings as it eating engine oil. Is this the cause of all probs??
Please help me to solve my problems. Also somebody suggest me a good CNG workshp in RWP/ISB.
Thanks in advance.
